The motorist, pulled over by an Indiana police officer because his Volvo had a broken tail light, jumped out of his car and fired his semiautomatic handgun 10 times, hitting the cop in the head, chest, hand and forearm.

James “Skip” Lockhart III, then 27, was killed on that July night in 2012 in a shootout with other officers, shortly after he ambushed Fortville police officer Matthew Fox.

Lockhart’s family is receiving unwelcome scrutiny yet again, this time because his stepfather founded the Indianapolis anti-aging clinic that allegedly supplied human growth hormone to Denver Broncos quarterback Peyton Manning.

The Al Jazeera documentary “The Dark Side,” claims Lockhart’s stepfather Dr. Dale Guyer and his Guyer Institute of Molecular Medicine supplied HGH to Manning and banned drugs to other athletes, and the explosive allegations in the film might very well spur law-enforcement officials to take a long hard look at Guyer’s Indianapolis clinic.

A spokesman for the U.S. Attorney’s Office in Indianapolis said he could not comment when asked if federal authorities would investigate the claims in “The Dark Side.” A spokeswoman for Marion County (Ind.) prosecutors also declined comment.

But South Florida attorney David Weinstein, a former federal prosecutor who also headed the Miami state attorney’s narcotics section, says he wouldn’t be surprised if the film moves law-enforcement officials to quietly investigate “The Dark Side” allegations.

“Any time a report like this comes out, local and federal authorities will say ‘let’s take a look at what is going on here,” Weinstein said.

Fox, according to the Indianapolis Star, was a member of a drunken-driving task force when he stopped Lockhart on July 27, 2012, because of the missing tail light.

Lockhart, whose rap sheet included arrests for felony battery, misdemeanor resisting law enforcement and possession of marijuana, refused to turn off his car or show his hands as Fox ordered. The he peeled out, with Fox in pursuit.

Video from a dash-cam in Fox’s police cruiser shows Fox jumping out of the Volvo with his weapon in his hand. He fires at Fox at close range before hopping back in the Volvo and driving away.

Fortunately for Fox, the officer was wearing a bulletproof vest. One bullet ricocheted off the officer’s hand and struck his forehead.

Lockhart crashed into a police car as he tried to escape after shooting Fox. He left his Volvo and shot at officers with an assault rifle, the Star reported. He was killed in the shootout with police.

A Guyer Institute spokeswoman declined to discuss the 2012 shooting or refer the Daily News to an attorney for Dale Guyer. Instead, she forwarded the News a statement issued by Guyer that denied the allegations in the Al Jazeera report.

Alex Rodriguez and Anthony Bosch also immediately denied the Miami newspaper report that linked the Yankee slugger to banned drugs, but Weinstein pointed out that the Biogenesis scandal that led to discipline for more than a dozen Major League Baseball players, including Rodriguez’s season-long suspension, also resulted in a federal indictment that named Bosch and A-Rod’s cousin Yuri Sucart as defendants.

Bosch is now serving a four-year prison sentence for his role in the Biogenesis scandal while Sucart was sentenced to seven months by a Miami federal judge last summer.

Prosecutors may quietly look into the allegations by subpoenaing Guyer’s medical and drug records, Weinstein said, to determine if any local or federal laws or drug regulations have been violated. Law-enforcement officials, he said, won’t be satisfied with denials from Manning, the Broncos and the Colts.

“What happens if someone dies or their health is negatively impacted?” Weinsten asked. “Prosecutors know their job is to protect the health and well-being of the public.”
